I'm not sure why this game has so many five-star reviews. This is probably the most basic porn game you'll come across. There's no nuance; you never really play the game, and it never feels like your choices, or rather lack thereof, have any impact on the game's progression. You're always going from point A to point B. You never truly deviate from the path laid before you. I understand that most Ren'Py games are visual novels. However, this is one of the most linear visual novels on this site, which begs the question of why it has such a high rating. You just keep moving forward, so this might as well be a slideshow. There's no way you can go wrong because the game looks after you and always steers you in the right direction, not that there is a wrong one.
The story, meanwhile, is rife with clichés. Loser protagonist? Check. Virgin? Check. Recently turned of age? Check. Massive dick? Check. This game offers nothing remarkable — except for the art style, which may be the "game's" only saving grace. Even so, if you truly adore this style, I would recommend playing some other particular game, which is far superior in terms of actual gameplay despite being built on the same engine.
As for the humor, a teenager starting his first year of high school might find enough amusement in the "hilarity" this game displays, and that's being generous. Every time the protagonist sees a woman, he pops a boner, and this theme continues throughout the story. It's like a joke that the developer thought was so funny and groundbreaking that it had to happen every time the protagonist interacted with a female character. Because otherwise, the scene would be incomplete! It intrigued me the first couple of times I saw it, but by the 20th time, I was sick of it.
To summarize, this is one of those games where you only care about unlocking the gallery because the "gameplay" isn't worth your time. I'm giving the game 2/5 stars because the art is genuinely good, but everything else falls flat, and if we're rating this as a game and not a collection of pornographic material, I can't give it a higher rating than I did.
